Milton Friedman said it best:
“The only way that the Treasury can redeem its debt to the Social Security Administration is to borrow the money from the public, run a surplus in its other activities or have the Federal Reserve print the money -— the same alternatives that would be open to it to pay Social Security Benefits if there were no trust fund. But the accounting sleight-of-hand of a bogus trust fund is counted on to conceal this fact from a gullible public”
Milton Friedman also said, You cannot simultaneously have free immigration and a welfare state. The entitlement programs are being impacted significantly by immigration, legal and illegal.
